Redmond, Wash.-based Microsoft saw its shares dropped 1.81% to $27.13 in after-hours action. While Microsoft has gained about 3.5% so far in 2013, it has lagged behind the broader markets over the past 12 months with a 7% slide.

Earlier this week FOX Business's Charlie Gasparino reported that Microsoft is exploring an investment in struggling PC maker Dell (DELL) as part of a joint venture. Dell is said to be in talks with a number of private-equity firms over a leveraged buyout.

Microsoft didn't address the Dell speculation in its earnings report on Thursday.
